- Splitted the code into an  architecture specific and a generic part
- Changed naming and formatting to follow the FreeRTOS code style guides

memguard: changed #ifdef names of headers and function names. Moved many definitions into the freertos config file

memguard: fixed mechanism for blocking tasks from running before the memguard_notify_new_task_created() is called for them.
We keep them suspended until this function is called.

memguard: code restructured in order to build properly with all the MemGuard framework included in the freeRTOS

memguard: CMake changed for MemGuard, restructured from library type to subdirectory. Files for multi-core moved inside freertos/extra/memguard from runtimes/memguard

memguard: improved comments, improved idention, renamed functions, changed functions signatures, moved files, moved #define elements, solved errors in pmu functions

memguard: removed usage of uxTaskGetSystemState() - moved memguard folder inside the extra folder of FreeRTOS

In freestanding mode GCC only provides stddef.h, but not stdlib.h
